摘　　要：目的:分析评价种植修复的远期效果。方法:将本院的最后一次复诊时,种植修复时间达到十年以上的病例纳入研究范围,对所植入的种植体功能状态,种植体周围组织的稳定性和种植体存留率等进行分析评价。结果:共211例患者,种植体845枚,符合本研究的纳入标准,仅为我院种植十年以上(1万多枚种植体)病例的很小部分。其中802枚种植体在正常行使功能,有33枚种植体曾有过修复机械并发症,种植体的存留率为94.9%。结论:研究表明我国的种植修复患者的长期回访率很低,本研究的结果虽不能完全反映我院种植十年以上病例的全部情况,但也能说明了种植修复治疗的远期可靠性。Objective： To analyze the long-term result of implant restoration. Methods： The study included211 patients with 845 implants. All patients with implant-supported prostheses were followed for at least 10 years. Survival rates, soft tissue health, and radiographic marginal bone loss of the implants were evaluated. Results： 43 implants failed during the first 3 years after placement and another 802 implants had stable fixed prostheses in function. The marginal bone loss around the implants was small and there were no signs of a peri-implant infection. The implant survival rate was 94.9%. Conclusions：Our study shows that follow-up rate of the patients with implant restoration is very low, the results of this study do not fully reflect the status of all cases with implant-supported prostheses more than a decade in our hospital, but can also demonstrate the long-term reliability of the implant restoration treatment.
